—says Indiana brickmaker.

MARTINSVILLE, INDIANA— Mr. Thomas D. Fleming,
manager of Martinsville Brick Co., says:

“After using Additive-A clay conditioner for a full
year, we are able to compare results. We found that
due to reduction of tempering water, we increased
our production by approximately 6 million brick units.
During this period we did not have a single complaint
from dealers on chippage, scumming, laminations

or variation in size. We wouldn't operate without
Additive-A because it helps us produce more and
finer quality bricks at less cost.”

New Silaneal Treatment
Gives Brick Lasting Beauty

Here’s a discovery that’s boosting brick sales throughout the country. It’s
Silaneal®, the new plant-applied sodium siliconate treatment that gives
brick lasting beauty . . . keeps even your most delicate hues clean and
free of discoloration. And as if this weren’t enough, Silaneal also helps
vou lower the suction rate of high absorbency brick to a controlled opti-
mum. In short, Silaneal gives brick more sales appeal!

Silaneal accomplishes so much because it makes brick water repellent
And water is a chief source of staining trouble. Water carries soil. soot.
ind other dirt into brick. Also, water leaches salts from brick or back-up
materials, and deposits them on the surface, forming efflorescence. By
causing brick to shed water, Silaneal stops these problems at their source

virtually eliminates staining. Treated brick stay clean in storage and

installation in all kinds of climates

Silaneal helps speed construction, too. Controlled suction rate means
proper hydration. Mortar stays workable longer . . . brick needs no soak-
ing. More mortar can be spread at a time, and more courses laid before
the joints are struck. Cleanup is generally reduced to a simple brushing;

the need for acid cleaning is minimized.

Low cost Silaneal is easy to apply by dip or spray methods. It’s non-

flammable and water-dilutable — there’s no fire hazard. Silaneal has been

evaluated in tests prescribed by the Structural Clay Products Research Test wall after cix months’ exposure

Foundation, and thoroughly field-proven in numerous buildings. in northern climate. Top four rows are

Open Letter to Members of A.S.S.E.

he clay pipe industry has progressed more in the past 15 years than in the past 100 years.

Clay pipe today is longer, stronger. straighter and has a fool proof joint. This progress outstrips

anything in the field of competitive forms of pipe.
All these improvements are heaped upon a product that was nearly perfect before any research was

done upon it.
The improvements are made on the pipe for one main objective,—to better serve the public in its dis-
in health—in service.

could be sure that his jobs would hold up forever. He could design and specify with full confidence

that his objectives would be fulfilled. The community, too, was assured a sound investment that would
outlast many, many bond issues on sewers of less quality products.

What are these great strides forward that pipe has experienced? They are enumerated here for the
engineer. If he did not know of them. he can be apprised here. If he knows of them, this is a review

and reminder for him.

The new clay pipe is longer

fter years of extensive experi-

mentation in field trials. the
clay pipe industry today almost uni-
versally offers the sanitary contrac-
tor clay pipe in lengths of 4 and 5
feet. The engineer building the sewer
has 20°. fewer joints to make. Cou-
pled with new joints joining materials
the longer pipe offers him a_ fool
proof sewer.

What are the advantages of long-
er pipe? Longer pipe will build a
sewer for a lesser investment. In
learning to make the longer pipe.
greater care had to be used in pre-
paring raw materials and in actually
making the pipe. Perfectly straight
and perfectly round pipe resulted.
These two factors. too. contribute to
lowering the cost of installing clay
pipe.

Already there is talk in the in-
dustry of going beyond the 5 foot
lengths. Since the pipe will with-
stand the beam loads there is a good
chance that the next major step in
leneth will be to 6 feet.

In developing the 5 foot lengths.
much thought was given to the in-
creased weight of the pipe. However.
the increase was not beyond the abi
itv of the construction industry to
handle the longer pipe in the same
wav that it handled the shorter pipe.
The thickness of the pipe wall was
not increased when the length of the
pipe was increased.

It has been noted so far that the
handling of the longer pipe is better
and therefore losses of pipe througt
handling reasons has been reduced

‘ onsiderably

Stays with 4+ length

Some parts of the country have
staved to the 4 foot lengths in sizes
below 8” in diameter. However. the
entire industry is making 5 foot
length in sizes of 8” diameter and
larger

It might be said that with the
thought of going to lengths beyond
the 5 foot, stronger new clay pipe of-
fered today indicates that the reduc
tion in weight may be possible. As
knowledge in the industry develops
about processing and selecting of ma-
terials, it is entirely probable that a
longer, stronger and lighter pipe will

result.

Strength

The new clay pipe is stronger

=o,

‘tronger pipe is now offered by the
industry and the strength comes
mainly from increasing the thickness
of the wall. In an 8” series pipe the
normal wall thickness is 11 L6th of
an inch; adding ‘ath of an inch to

in thick

ness and a great deal of strength to

the wall thickness adds 15°
the pipe. As a matter of fact the in
crease in strength was about propor
tional to the increase in the thickness

of the wall.

However, all of the strength did
not result from this one factor. Over
the past ten years the industry has
developed new methods of clay prepa
ration, of grinding, of bringing out
plasticity in strength. It has developed
new methods of forming all of which
put together added to strength. Sewe!
projects are requiring pipe to be laid
deeper and deeper. In many cases
live loads are carried by the soil

this challenge with greater strength

in its produc t.

Contractors Rally Again

In one area of the country almost
no standard strength pipe is used but
it is all extra strength pipe. Once
again the contractor has rallied to
the developments in the industry. He
has accepted and approved the longer
length and he is learning to use extra

strength pipe exclusively,

Joints

The new clay pipe joints are fool proof

he new clay pipe joints are made

of plastic materials. The two
basic materials used today are poly
vinyl chloride which is cast into the
bell and on the spigot. The two poly
vinvl chloride surfaces then are
rammed together. making a_ tight
joint which eventually welds and be
comes monolithic The second yornt
commonly used is a polvester joint
with a rubber gasket. The polyester
is cast into the bell and on the socket
\ void is left in the casting where a
rubber gasket is inserted

Both of these materials perform
very well and as one spokesman for
the Industry said. Jointing materials
used with vitrified clay pipe are high
quality materials which lend them
selves to perfection in design. As
more experience is gained the indus
try is gradually going toward a stand
ardization in thinking on design. The
major objective of jointing is to ob
tain a water-tight joint. All joints are
tested to 5 lbs. per square inch pres
sure and the new joint easily with
stands this test and other tests in
cluding those up to 50 and 100 Ibs
pressure. The joint must have a cet
tain amount of resilience to withstand
beam load and it must have long life
The new plastic joints fulfill these
requirements besides making the
sewer water-tight.

Newer themical resins are being
studied for the jointing of vitrified
clay pipe and are currently being
produced in increasingly larger
amounts. These are the epoxy resins
and the polyurethane resins

Since the success of the new joint

depends upon more accurately made

pipe. the developments throughout
the industry therefore have worked
hand in hand. The improved process

ing which made possible the longer

pipe also made possible the plastic
joint.

In discussing the matter of econo
my with many contractors the gen
eral opinion is that in spite of paying
for the factory made joint. the con-
tractor actually has a greater profit
from his job because much less labor
is used in laying the pipe. He furthet
has the assurance that he can pass the
required tests when he gets the line
in and he can lay this pipe under
much more severe conditions because
of the joints

There is no field work necessary

to manipulate the joints. Human

Practically all of the producers are offer-
ing plastisol and polyester factory made

going to unglazed pipe production.

Of the four advances noted above, the
new joints or couplings being produced
and the trend to unglazed pipe are of
primary concern. The work done by Al
Reed and his staff at the NCPMI Research
Laboratory at Crystal Lake, Illinois has de-
veloped the polyester and rubber O-Ring
joint to the point where it will be con
sidered standard in the industry, at least
on large sizes.

The move toward unglazed pipe has been
slow but significant in this instance has been
the ready acceptance of unglazed pipe by
leading engineering firms and cities and
towns throughout the area where the un-
glazed pipe has been offered for sale.

With the caliber of professional research
and development being carried on by the
Clay Pipe Industry, it is logical to expect
great advances in the design of pipe and
joints and installation methods.

M or breakthroughs in research on struc
tural clay products were achieved last
year (1959) that should greatly enhance
the competitive standing of these prod
ucts in the building materials market

Just one of these breakthroughs was the
beginning at plant level of work on com-
mercial adaption of the Structural Clay
Products Research Foundation's new light-
weiaht a-qregate

This should result in end products that are
ighter in weight and with closer dimensional
tolerances. In addition, it is expected that
drying and burning time in the manufac
turing process will be substantially reduced
Lighter weight aggregate-based products
should also reduce transportation costs and
facilitate handling

Our introduction of Vitri-Seal joints for
clay sewer pipe during 1959 is important
This new compression-type joint is self
aliqning, leak-proof, acid and alkali resist

hile vitrified clay sewer pipe has made

enormous progress since the end of
the War in the improvement of quality, de-
velopment of factory-made joints, higher
strengths and longer lengths, it has at the
same time been losing ground rapidly in
the house connection field to inferior com-
petitive materials.

Vitrified clay pipe made in longer lengths
with root-proof plastic joints is the finest
piping material now manufactured for house
sewers. It is the only truly permanent prod-
uct now available to the home owner.

The inferior competing materials by rea-
son of massive and intelligent promotion
and advertising are continually increasing
their share of the house sewer market.

The time has come for a vigorous pro-
motion and consumer advertising program
to tell the merits of the new clay pipe with
factory joints to the plumber and consumer
as well as architects and sanitary engineers.
Unless our efforts along this line are in-
creased, we face a continually dwindling
market. We feel that the time to expand
our activities is right now and hope that
the whole Industry will get together in a
vigorous promotional effort.

ba Robinson Clay Products Co. has an un-
bounded faith in the future of the Clay
Pipe Industry

Our faith is exemplified in our far-reach-
ing research and development program for
new products, techniques of manufacture
and new uses for clay pipe. Our faith is
exemplified in the millions of dollars we
are currently spending to modernize our
manufacturing facilities to make longer,
stronger pipe of better quality. Our faith
is exemplified in our jointing program for
clay pipe products in which we developed
the most widely used principle in the indus-
try for pre-fabricated joints: the use of plas-
tisols and of double ball! joints. Our faith
is exemplified by our hard hitting sales
program to market the products of our

Pipe Executives Comment

| pte centuries of experience, clay pipe
has dramatically demonstrated its dur
ability in all types of sewer applications
The industry's research and development
therefore, are mainly centered
on transmitting the proven benefits of clay
pipe to customers through innovations which

activities

will satisfy their needs

Among the significant innovations are
factory-made compression joints. These joints
permit pipe to be installed more rapidly
allow a quick back-fill and guard against
infiltration. Not only does this development
reduce the cost of installation, but it pro
vides insurance against human error by
bringing factory quality control right into
the ditch. Additionally, the ability of the
flexible compression joint to resist infiltra
tion reduces the load placed on sewage dis
posal plants during peak periods. This ad
vantage in itself provides considerable sav

ings for taxpayers as it reduces the size re-
quired for the treatment facility.

Further evidence of the industry's recog-
nition that its progress is related directly
to its ability to serve the market, is the
increase in pipe length. Since the end of
World War II, the length of sewer pipe has
been increased as much as 150 percent.
This reduces the number of joints required
while cutting installation costs and time.

Market oriented research and develop-
ment activities are vitally necessary to in-
sure a continued pattern of growth by the
clay pipe industry. While excellent progress
has already been made along these lines, fu-
ture requirements dictate substantially in-
creased attenton to this area.

pipe was developed. The work on

large pipe production may lead into
a method which will make possible
the manufacture of pipe beyond 36”
in diameter.

Prefiring of the clay before form-
ing is also under consideration. Al-
ready some manufacturers are adding
the prefired clay up to possibly 30°¢.
This can go to 50% and maybe even
80°. of the final pipe. This would
eliminate warping, twisting and other
deformation in firing. It would re-
duce shrinking and if the right kind
of prefiring is done on the material
it would reduce the weight of the
final product. In the manufacturing
process, it would cut down the fir-

must be used in the bell and on the

there will be significant.

would further reduce jointing and
one that would resist beam loads at
the same time. Chemical resistance
as far as the pipe itself is concerned
is no problem. Strength, too, must be
increased because pipe installations
are going deeper and deeper which
means that the loads on the pipe are
heavier and heavier.

Research has accomplished a great
deal for the clay pipe industry al-
ready, however. as was previously
pointed out. the surface has only been
scratched and the future points to
developments yet unforeseen. There
will be lengths, greater

What Price Quality?

Tere is really no such thing as cutting corners when it comes to mak-
ing brick, tile, pipe, refractories or abrasives. Quality raw materials
put into the products insure quality products as a result.

For instance, good colored finishes on brick and tile can only come
from quality colors prepared specifically for the job. Clay pipe joints
are best produced, not with the cheapest PVC or Polyester but with
carefully compounded chemicals and plastics. It might be cheaper to
build small periodic kilns for firing but it's the continuous larger kilns
that save fuel and labor—and cut losses.

First cost, which in too many instances is the primary factor in de-
termining an investment in a raw material, additive or machine, usually
is not the best basis on which to select products.

We heard the other day of a brick man who wants to go into the pro-
duction of lightweight clay block. He has a machine, he has kiln space
available, but is stopped by the cost of aggregate. He wants to pay $2
a yard and the going price is $3. He couldn't make his own aggregate
for that low price and it's questionable if his supplier is making out on
the $3 price.

In just about every case quality ware or service rendered far outstrips
additional costs, provides greater profits through fewer rejects and sat-
isfies customers.

If you want to get quality results, make quality products, and obtain
consistant profits you've got to put quality raw materials together and
make the products with quality equipment.

rom time to time readers of BRICK AND

CLAY RECORD have expressed interest in

the manufacture of clay products other than
brick, clay pipe and refractories. The manufac-
ture of quarry tile, with many of the same pro-
duction problems as other clay products, has
not been publicized over the past decade. In
this story, the quarry tile industry is shown
to be as progressive as many brick manufac-
turers, and it is shown that by no means is the
industry passing out of the heavy clay products

A Well-Known Fact

It is well-known that ball-milling
the blend wet tends to reduce the vit
rification point of the body and pro
duces a smoother surface. From the
ball mill. the slurry is pumped to a
trough-type dryer under which burn
ers are located. Most of the moisture
is removed from the slurry and the
residue is then sent to a hammermill
type pulverizer with the proper
amount of motsiure for pressing hav
ing been retained in the body

Abrasive wear in dry pan operation Is
rough on plow points. Yet a simple cure is
effected by a few beads of Stoody Borod.
It is unnecessary to hard-face the whole
wearing surface. Notice that the hard-
facing alloy is applied in stringer beads
spaced an inch or so apart. Loose clay
packs between the stringers forming an
effective, wear resistant pad, thus saving

unnecessary waste of alloy materials.

A direct comparison between the hard-
faced plow and the unprotected piece shows
how efficiently the Borod maintains size
and shape. Both plows operated approxi-

mately the same number of hours.

techniques is yours in the Stoody Guidebook.

LEAD HELPS FIND NEW CUSTOMERS FOR BRICK

The sparkling facade that lends so much eye-appeal
to the new Lenox Square Branch of Davison’s famous
Atlanta Department Store derives much of its vividness
from lead. The architects, Toombs, Amisano & Wells,
capitalized on free-flowing lead glazes to impart a
permanent, glistening red beauty to the exterior of
this new mecca of superior merchandise.

No matter where you look today, you find examples of
ceramics that have been beautified by lead and found
wider markets through its use. You see it on the ex-
teriors of new buildings... on dinnerware .. . in kitchen
and bathroom tiles, and on light aggregate block. And
there are good reasons for this.

Lead glazes not only apply a permanent beauty to
ceramics... but do it economically. They have high
flexing power, impart low surface tension and low

viscosity to glazes...enable you to build-in a wide

range of vivid colors that require a bare minimum of
maintenance over the years

And these are just a few of the profitable advantages
to be found in lead-glazed ceramics. Get the full details.

Better ceramic plants are built
by ceramic plant specialists

A “better ceramic plant” produces a quality clay product at a
lower plant operating cost. Its kilns and dryers are tailor-fitted
to a specific product and output, and operate with a minimum
fuel input. Its up-to-date grinding and handling equipment is
economic of both power and space. Its materials “flow line”
has neither waste motion nor waste space. Its operation is
economical of both man-power and man-energy, and reduces
and simplifies maintenance.

This is the kind of ceramic plant Hendryx will build for you.
When you are contemplating a new ceramic plant, it will pay
you to consult Hendryx — known from coast to coast.

HOW ABOUT A
POTASSIUM
SILICATE ?

If you are revising formulations or working on new ones,
these properties of the potassium silicates (our Kasil

may be of interest

ELECTRICAL PROPERTIES... The electrical con-
ductivity of an anhydrous potassium silicate is lower than
that of sodium silicate. Potassium silicate thus is often
preferred in cements that are used in combining certain
parts of electrical systems. Similarly it is used in potting
compounds for sealing resistance coils and as an adhesive

for reconstituting mica into useable insulation

NO BLOOMING ... Potassium silicate coatings do not
develop a conspicuous white carbonate film or efflores-
cence on exposure to the atmosphere. For this and other
reasons Kasil is preferred for pigment binders, for

asbestos cement shingles, paints, and decorative coatings

REFRACTORINESS. .. . Potassium silicates soften and
flow at a higher temperature than corresponding sodium
silicates even at the same alkali to silica mol ratio. Hence,
Kasils are advantageous as high temperature binders of

various types

O'Hare International Airport: “This
masonry fill, because of its granular
quality. settles immediately and ef-

stufling or cramming and no waiting
for the insulation to settle for addi

Stronger
than Concrete

Furane’s Epibond produces a bond line
between concrete and steel 4 times
stronger than concrete itself

Now you can obtain a reliable, permanent bond between

steel and concrete with Furane’s EPIBOND Epoxy Dowel
Grouting Compound — easily, at low cost. Regular caulking
equipment serves in bonding bolts, dowels, rebar, ladders and
other metal parts to concrete structures

Enibond is easy to handle, non-toxic and non-dermatitic

It is thermosetting and cures chemically at room temperatures,
for a bond completely unaffected by water or chemicals
present in the concrete

Coated with Epibond Dowel Grouting Compound,
the steel dowel in the illustration is being positioned
in the horizontal hole for permanent bonding into
the concrete.

Because of the many variables in clay products production, Steele has always been conservative
in claims for its equipment. This excerpt from a letter from Mr. Albert R. Martin of Southwestern

Brick and Tile Co. is an example of statements made by many other more-than-satisfied customers.

“The No. 40 Machine has more than met all our expectations. Eighty thousand brick in 8 hours is
nothing for this machine to do. We get a much higher quality product and with less power per
thousand than with our former machine. Operation is wonderfully smooth, daily maintenance a pleas-

ure. Your entire organization is to be congratulated on this machine.”

The 40F is a single drive machine with a capacity of 8,000 to 15,000 brick per hour and relative
tonnage in holloware. It is available with a wide range of sizes, types, pitches, and designs of extru-
sion augers to handle any type material. Heavy construction and the well known Steele accessibility

and adaptability make this a truly outstanding piece of equipment.
